• a(1)=7; if n = Product p_i^e_i, n > 1, then a(n) = Product p_{i+4}^e_i.at n=47A045970
• Numbers of the form (11^i)*(13^j).at n=16A108090
• Number of (1,0) steps in all paths of length n with steps U=(1,1), D=(1,-1) and H=(1,0), starting at (0,0), staying weakly above the x-axis (i.e., in all length-n left factors of Motzkin paths).at n=11A132894
• a(n) = A276086(A276086(n)), where A276086 is the primorial base exp-function.at n=47A276087
• Lexicographically earliest sequence of nonnegative integers such that a(1)=3 and the sequence is p-periodic mod p for any p > 0.at n=14A284148
• Square array A(n,k), read by descending antidiagonals, where A(1, k) = A388984(k), and for n > 1, A(n, k) = A003961(A(n-1), k).at n=49A388981
